There is a quest that tells the tale of a young Wizard who checked a book out of the Library - perhaps that is what the player is referring to in their post. But just to clarify, you cannot check books out of the libraries of the Spiral, you can however, purchase Treasure Cards!

I also saw someone say they were messing around with the Krokonomicon and something happened and they poofed somewhere else...do you need to finish Krokotopia to do this? Or were they roleplaying or something?
